... The catalogues of central velocity dispersion and maximum velocity of rotation . HyperLeda home | Documentation | Search by name | ... This catalogue is an updated version of the catalogue distributed as an Appendix to a paper by Prugniel and Simien (1996) . ... It contained 12858 velocity dispersion and 1613 rotation measurements in december 2007, for respectively 7601 and 801 objects and from 418 and 231 references. ... The description of an updated version of this compilation is here . ...

... 22.Reference Frames . ... Inertial Forces . 23a. The Centrifugal Force . ... When calculating the motions of the oceans and the atmosphere, it is much easier to use reference points on the rotating Earth and add a centrifugal force to all equations. ... The rest arises because the Earth is not a perfect sphere: the centrifugal force of its rotation causes its equator to bulge out , making the surface there more distant from the Earth s center and thus weakening the gravitational pull. ...

Optical Filters . The polarizer quads were also designed to map onto a four-faceted WFC configuration and, consequently, also require a partial filter rotation of -33 degrees to move the filter quadrant 1 (nominal polarization angle 135 degrees ) into WFCs 2 and 3, with some vignetting of both camera fields. Several additional partial rotations have been added to allow observations with different polarization angles on the same CCD. ...

... We have mapped the central region of the spiral galaxy NGC 1808 in the 12CO J=1-0, J=2-1, J=3-2 lines and measured 13CO J=1-0, J=2-1, C18O J=1-0, HCN J=1-0 and an upper limit on CS J=2-1 at the central position. ... The line intensity ratios indicate that the central molecular gas of NGC 1808 is in a state of high excitation compared with giant molecular clouds in the disk of the Milky Way. ... A simple estimate of the pressure felt by these clouds leads to further constrains on their properties. ...
